Energy released in the fission of a single $_{92}U^{235}$ nucleus is $200 \, MeV$. The fission rate of a $_{92}U^{235}$ fuelled reactor operating at a power level of $5 \, W$ is

Two lighter nuclei combine to form a comparatively heavier nucleus by the relation given below:
${ }_{1}^{2} X +{ }_{1}^{2} X ={ }_{2}^{4} Y$
The binding energies per nucleon of ${ }_{1}^{2} X$ and ${ }_{2}^{4} Y$ are $1.1 \, MeV$ and $7.6 \, MeV$ respectively. The energy released in this process is in $MeV$.

$_1H^1 + _1H^1 + _1H^2 \to X + _{+1}e^0 + \text{energy}$. The emitted particle $X$ is:

In an atomic bomb,the energy is released due to

For nuclei with mass number close to $119$ and $238$, the binding energies per nucleon are approximately $7.6 \text{ MeV}$ and $8.6 \text{ MeV}$ respectively. If a nucleus of mass number $238$ breaks into two nuclei of nearly equal masses, what will be the approximate amount of energy released in the process of fission (in $\text{ MeV}$)?

$A$ nuclear reactor process is said to be critical when the value of the multiplication factor is .......
